Design and Research on the Contour Strip of Self luminescent Reflective Highway Tunnel
To solve the problem of small visual overall range and concentrated visual points in the existing contour strip design,the design of self luminous reflective highway tunnel contour strips was studied.Multi-point contour strips on both sides of the highway in a symmetrical arrangement were set up,same installation height with the driver's line of sight height,and combining with the distribution characteristics of the driver's gaze points for guidance setting.Based on the type of tunnel,with the goal of optimizing the lighting environment,the specific spacing values of the tunnel contour strip facilities were modified,and LED multi-point contour strips were combined to improve the roadside boundary contour of the tunnel maintenance track.The experimental results show that after setting up the reflective ring,the visual points of the testers are dispersed.When the distance between the reflective rings is 250 m,the testers can see the reflective ring as far as about 850 m,which has a good effect on improving the visual area.By optimizing the design,a good effect of self luminous reflective highway tunnel contour strip has been achieved,providing assurance for the safety and comfortable driving of highway tunnels.
